Unique Βenefits

No electricity
Nero softeners work entirely without electricity, thanks to its full-automatic hydraulic functioning.
No programming
You just need to regulate the incoming hardness and the Nero softener is ready for use.
Very compact dimensions
Nero softeners have very compact dimensions, which allows to find the right spot for installation far more easily than with most traditional softeners: in (low) cellars, in the garage, but also under the sink, in the bathroom, and so on.
Restricted salt and water consumption
Nero softeners are friendlier for the environment and use significantly less salt and water in the course of the regeneration. Furthermore, the duration of the regeneration is very short.
Large exchange velocity and exchange capacity
In spite of their smaller dimensions, our softeners dispose of a very large exchange capacity and the best exchange velocity in the world of softeners: up to 400 bedvolumes per hour.
Very easy installation
All you have to do is connect the appliance hydraulically and regulate the incoming hardness manually with a hex key. The result is an installation time that is remarkably shorter than is the case with classic softeners, and also a lot easier.
Incorporated filter screens
At the entrance, there is a filter of 300 micron. Furthermore, each resin bottle is delivered with 2 incorporated 80 micron filter screens that are cleaned automatically during each regeneration.
Synthetic material of very high quality
Entirely composed of synthetic material of very high quality, so that all components are free of corrosion and the appliance has no effect whatsoever on the aggressivity and corrosivity  of the water to be treated.
